QML PathView Element

This property holds the number of items in the model.

This property holds the index of the current item.

The delegate provides a template defining each item instantiated by the view. The index is exposed as an accessible index property. Properties of the model are also available depending upon the type of Data Model.

The number of elements in the delegate has a direct effect on the flicking performance of the view when pathItemCount is specified. If at all possible, place functionality that is not needed for the normal display of the delegate in a Loader which can load additional elements when needed.

Note that the PathView will layout the items based on the size of the root item in the delegate.

Here is an example delegate:

     Component {
         id: delegate
         Column {
             id: wrapper
             Image {
                 anchors.horizontalCenter: nameText.horizontalCenter
                 width: 64; height: 64
                 source: icon
             }
             Text {
                 id: nameText
                 text: name
                 font.pointSize: 16
                 color: wrapper.PathView.isCurrentItem ? "red" : "black"
             }
         }
     }

This property holds the maximum distance from the path that initiate mouse dragging.

By default the path can only be dragged by clicking on an item. If dragMargin is greater than zero, a drag can be initiated by clicking within dragMargin pixels of the path.

This property holds the rate at which a flick will decelerate.

The default is 100.

This property holds whether the view is currently moving due to the user flicking the view.

This property holds the component to use as the highlight.

An instance of the highlight component will be created for each view. The geometry of the resultant component instance will be managed by the view so as to stay with the current item.

The below example demonstrates how to make a simple highlight. Note the use of the PathView.onPath attached property to ensure that the highlight is hidden when flicked away from the path.

 Component {
     Rectangle {
         visible: PathView.onPath
         // ...
     }
 }

See also highlightItem and highlightRangeMode.

highlightItem holds the highlight item, which was created from the highlight component.

See also highlight.

This property holds the move animation duration of the highlight delegate.

If the highlightRangeMode is StrictlyEnforceRange then this property determines the speed that the items move along the path.

The default value for the duration is 300ms.

A user cannot drag or flick a PathView that is not interactive.

This property is useful for temporarily disabling flicking. This allows special interaction with PathView's children.

This property holds the model providing data for the view.

The model provides a set of data that is used to create the items for the view. For large or dynamic datasets the model is usually provided by a C++ model object. Models can also be created directly in QML, using the ListModel element.

Note: changing the model will reset the offset and currentIndex to 0.

See also Data Models.

This property holds whether the view is currently moving due to the user either dragging or flicking the view.

The offset specifies how far along the path the items are from their initial positions. This is a real number that ranges from 0.0 to the count of items in the model.

This property holds the path used to lay out the items. For more information see the Path documentation.

This property holds the number of items visible on the path at any one time.

These properties set the preferred range of the highlight (current item) within the view. The preferred values must be in the range 0.0-1.0.

If highlightRangeMode is set to PathView.NoHighlightRange

If highlightRangeMode is set to PathView.ApplyRange the view will attempt to maintain the highlight within the range, however the highlight can move outside of the range at the ends of the path or due to a mouse interaction.

If highlightRangeMode is set to PathView.StrictlyEnforceRange the highlight will never move outside of the range. This means that the current item will change if a keyboard or mouse action would cause the highlight to move outside of the range.

Note that this is the correct way to influence where the current item ends up when the view moves. For example, if you want the currently selected item to be in the middle of the path, then set the highlight range to be 0.5,0.5 and highlightRangeMode to PathView.StrictlyEnforceRange. Then, when the path scrolls, the currently selected item will be the item at that position. This also applies to when the currently selected item changes - it will scroll to within the preferred highlight range. Furthermore, the behaviour of the current item index will occur whether or not a highlight exists.

The default value is PathView.StrictlyEnforceRange.

Note that a valid range requires preferredHighlightEnd to be greater than or equal to preferredHighlightBegin.

This attached property is true if this delegate is the current item; otherwise false.

It is attached to each instance of the delegate.

This property may be used to adjust the appearance of the current item.

     Component {
         id: delegate
         Column {
             id: wrapper
             Image {
                 anchors.horizontalCenter: nameText.horizontalCenter
                 width: 64; height: 64
                 source: icon
             }
             Text {
                 id: nameText
                 text: name
                 font.pointSize: 16
                 color: wrapper.PathView.isCurrentItem ? "red" : "black"
             }
         }
     }

This attached property holds whether the item is currently on the path.

If a pathItemCount has been set, it is possible that some items may be instantiated, but not considered to be currently on the path. Usually, these items would be set invisible, for example:

 Component {
     Rectangle {
         visible: PathView.onPath
         // ...
     }
 }

It is attached to each instance of the delegate.

This attached property holds the view that manages this delegate instance.

It is attached to each instance of the delegate.

This handler is called when the view stops moving due to a flick.

This handler is called when the view is flicked. A flick starts from the point that the mouse or touch is released, while still in motion.

This handler is called when the view stops moving due to user interaction. If a flick was generated, this handler will be triggered once the flick stops. If a flick was not generated, the handler will be triggered when the user stops dragging - i.e. a mouse or touch release.

This handler is called when the view begins moving due to user interaction.

Decrements the current index.

Note: methods should only be called after the Component has completed.

Increments the current index.

Note: methods should only be called after the Component has completed.
